THIS MANUAL

Installer: Please leave this
manual with the product.

WARNING! Heat alarms are not life safety devices and are not designed to
detect smoke or fire. Heat alarms detect temperatures of 135°F or greater,
and are intended to be used as supplements to smoke alarms by provid­ing early warning. See the IMPORTANT SAFETY INFORMATION section of
this manual.

NOTE A: Maximum alarm coverage has been determined by UL to provide detection
time equal to sprinkler devices spaced at 10-ft intervals (100 square foot area) on a
smooth ceiling 15 ft 9 in. high. Higher ceilings can adversely affect detection time. In
some instances, earlier detection may be obtained by reducing the distance between
detectors. See the latest edition of the NFPA 72E, Automatic Fire Detectors.
NOTE B: Maximum distance is measured from any wall partition or ceiling projection
extending down more than 12 inches.

•

This heat alarm is designed to be used inside a single family
building only. In multi-family buildings, each individual living

unit should have its own heat alarm. Do not install in nonresi­dential buildings or places which house many people like hotels,
motels, dormitories, hospitals, nursing homes, or group homes.
This heat alarm is not a substitute for a complete alarm system.

•

Heat alarms should be used in conjunction with smoke alarms
in order to provide early warning of heat, smoke or fire. In addi-

tion, smoke alarms should be installed in every bedroom and on
every level of the home.

•

Heat alarms may not alert every household member every
time. There may be limiting circumstances where a household

member may not hear the alarm (e.g., outdoor or indoor noise,
sound sleepers, drug or alcohol usage, the hard of hearing,
etc.). If you suspect that this smoke alarm may not alert a
household member, install and maintain specialty smoke
alarms. Current studies have shown smoke alarms may not
awaken all sleeping individuals, and that it is the responsibility
of individuals in the household that are capable of assisting
others to provide assistance to those who may not be awak­ened by the alarm sound, or to those who may be incapable of
safely evacuating the area unassisted.

•

This heat alarm can only sound its alarm when it detects
temperatures of 135°F or greater. Heat alarms do not detect

smoke, flame, or gas. In some fires, hazardous levels of toxic
chemicals and smoke can build up before a heat alarm will oper­ate. Temperatures may not reach 135°F to activate the heat
alarm QUICKLY ENOUGH to ensure safe escape.

•

Heat alarms should be used to supplement smoke alarms.

This alarm may not always detect slow, smoldering, low heat pro­ducing fires, and fires that are in a different room than the heat
alarm. In addition, heat from a nearby fire may bypass the heat
alarm.

•

Heat alarms have limitations. This heat alarm is not foolproof
and is not warranted to protect lives or property from fire. Heat
alarms are not a substitute for insurance. Homeowners and renters
should insure their life and property. In addition, it is possible for
the heat alarm to fail at any time.

HEAT ALARM PLACEMENT

Heat alarms give an audible warning when the temperature at the
alarm reaches 135°F. Heat alarms are ideal for kitchens, garages,
basements, boilers rooms, attics, and other areas where there are
normally high levels of fumes, smoke, or dust which are also areas
where smoke alarms should not be installed due to risk of false
nuisance alarms.

The National Fire
Protection Association’s
(NFPA) minimum require­ment, as stated in
Standard 72, Chapter 2,
reads as follows:

“2-2.1.1.1 Smoke detec­tors shall be installed out­side of each separate
sleeping area in the imme­diate vicinity of the bed­rooms and on each
additional story of the fam­ily living unit including
basements and excluding
crawl spaces and unfin­ished attics. In new con­struction a heat detector
also shall be installed in
each sleeping room.”

In addition, the California State Fire Marshal states: “Early
warning fire detection is best achieved by the installation of fire
detection equipment in all rooms and areas of the household
as follows: A heat detector installed in each separate sleeping
area (in the vicinity, but outside the bedrooms) and heat or
smoke alarms in the living rooms, dining rooms, bedrooms,
kitchens, hallways, attics, furnace rooms, closets, utility and
storage rooms, basements and attached garages.”

HEAT ALARM LOCATIONS

•

Install a heat alarm as close to the center of the ceiling as
possible. If this is not practical, mount no closer than 4 inches
from a wall or corner.

•

If ceiling mounting is not practical or the mounting surface
becomes considerably warmer or cooler than the room (such
as a poorly insulated ceiling, below an unfinished attic or an
exterior wall) and if local codes allow, install heat alarms on
walls, between 4 and 12 inches from ceiling/wall intersections.

•

Install heat alarms on peaked, cathedral,
or gabled ceilings 3 feet from the highest
point (measured horizontally).

•

In a room with open joists or beams, all
ceiling mounted heat alarms shall be
located on the bottom of joists or
beams – not in joist channels.

•

Heat alarms installed on an open­joisted ceiling shall have their
smooth ceiling spacing reduced to
no more than half of the listed
spacing when measured at right
angles to solid joist.

of the hole locations and insert anchors into holes.

4. Use mounting screws to secure mounting bracket to ceiling
or wall.

5. Lift open battery pocket door.

6. Connect new 9-volt battery to
battery connector inside battery
pocket. BE SURE BATTERY IS
SECURELY CONNECTED. Heat
alarm may beep briefly when

snapping it into place. (For tam­per-resist, use long-nosed pliers
to remove thin plastic from
notch on heat alarm edge.)

8. Position heat alarm to
mounting plate and turn
clockwise to lock into
place. To engage tamper­resist feature, insert pin into
notch on edge of heat alarm after alarm is properly positioned
in base. See instruction #7 on the previous page. NOTE: The
tamper-resist pin must be removed to change the batteries
and replaced when done.

NOTE: Heat alarm will not mount to plate if battery is not installed.

9. Test heat alarm. See TESTING THE HEAT ALARM.

WARNING:

DO NOT connect this heat alarm to any
other detector or electrical device. Doing
so will cause the heat alarm to operate
improperly or fail to operate.

DO NOT install heat alarms:

•

In areas with high humidity, like bathrooms or areas near dish­washers or washing machines. Install at least 10 feet (3 meters)
away from these areas, if possible.

•

Near air returns, heating and cooling supply vents, fans, deco­rative objects, window molding etc. that may prevent heat from
entering the unit thus interrupting its alarm.

•

In rooms where temperatures may fall below -10°F (23°C) or
rise above 100°F (38°C).

•

Near fluorescent lights - electrical noise and flickering may
affect the alarm’s operations.

Mobile home installation

For mobile homes built after 1978, install heat alarms as directed
above. For mobile homes built before 1978, install heat alarms on
an inside wall between 4 and 12 inches from the ceiling. (Older
mobile homes have little or no insulation in the ceiling which may
affect the heat alarm’s ability to detect heat properly.) This is
especially important if the ceiling is unusually hot or cold.

PRACTICE FIRE SAFETY

If the heat alarm sounds its alarm horn, and you have not pushed
the test button, it is warning of a dangerous situation.
Your immediate response is necessary. To prepare for such
occurrences, develop family escape plans, discuss them with
ALL household members, and practice them regularly.

•

Expose everyone to the sound of the smoke alarm and heat
alarm and explain what the sounds means.

•

Determine TWO exits from each room and an escape route to
the outside from each exit.

•

Teach all household members to touch the door and use an
alternate exit if the door is hot. INSTRUCT THEM NOT TO
OPEN THE DOOR IF THE DOOR IS HOT.

•

Teach household members to crawl along the floor to stay
below dangerous smoke, fumes, and gases.

•

Determine a safe meeting place for all members outside the
building.

WHAT TO DO IN CASE OF A FIRE

1. Don’t panic; stay calm.

2. Leave the building as quickly as possible. Touch doors to
feel if they are hot before opening them. Use an alternate
exit if necessary. Crawl along the floor, and DO NOT stop
to collect anything.

3. Meet at a prearranged meeting place outside the building.

4. Call the fire department from OUTSIDE the building.

5. DO NOT GO BACK INSIDE A BURNING BUILDING. Wait for
the fire department to arrive.

These guidelines will assist you in the event of a fire. However, to
reduce the chance that fires will start, practice fire safety rules
and prevent hazardous situations.
